In winter, after a snowfall, many people have trouble getting the car out of the driveway if the garage is below the level of the road. if the coefficient of static friction between tires of normal wear and snow is 0.14, what is the maximum incline of a driveway so that a four- wheel-drive vehicle can get up on the road during the winter?

Abaseball is thrown a distance of 20 meters. what is its speed if it takes 0.5 seconds to cover the distance

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
